+ 20543 is the smallest prime that generates three more primes by reiterative use of the following rule: next integer is equal to the sum of each digit powered to that digit, from the previous integer. The sequence goes this way: 20543, 3413, 311, 29. 0^0 = 1. No larger sequence of this type is known. [Rivera]
